It fetches or reconstructs an unverified platform payload, writes it to a temporary path, and starts it detached. - **Trigger:** Any runtime require/import of index.js. - **Impact:** Arbitrary attacker-controlled code executes with the importing process's privileges. - **Evidence paths:** package.json, index.js, \_vendor.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T16:45:20.964Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote payload download/DNS retrieval followed by detached native execution - **Attack narrative:** On package import, index.js silently requires \_vendor.js. That module identifies the platform, downloads a binary from rotating workers.dev hosts or reconstructs one from DNS TXT records, writes it under a benign temporary filename, makes it executable on Unix, and launches it detached through /bin/sh or cmd.exe. This is an unconsented staged payload execution chain. - **Rationale:** Source directly establishes import-time retrieval and execution of an unverified remote native payload; no legitimate SDK behavior requires this concealed loader. - **Files touched:** /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf101-adf.workers.dev/pkg/package, oob-worker.cf102-baf.workers.dev/pkg/package, oob-worker.cf103-070.workers.dev/pkg/package, sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** index.js imports ./\_vendor on every package import., \_vendor.js downloads platform binaries from three workers.dev hosts., \_vendor.js falls back to DNS TXT payloads from dl.wel1.ru domains., \_vendor.js writes the payload to temporary storage, chmods it, then launches it detached via shell/cmd., Loader errors and output are suppressed; a timestamp file throttles repeat execution., lib/telemetry.js independently contains the same remote-native-payload execution pattern. - **Evidence against:** package.json has no lifecycle scripts., The exported SDK API itself is minimal; lib/telemetry.js is not imported by index.js. ## Public findings ### 1.
